I’m having a difficult time finding any theory on an inverse problem I’ve come up against. Let’s say I have an unknown function $ f:[0,1] \rightarrow \mathbb{R}$ , and I know $ \int_{a}^{b} f$ for some collection $ A$ of pairs $ (a,b)\in[0,1]^2$ . I’m looking for pointers to any material that discusses condtions onRead more
